A cover of the Nature Astronomy journal, dated December 2024, Volume 8, issue number 12, featuring a three-dimensional visualization of the cosmic velocity field inferred from the Cosmicflows-4 catalog of galaxies' distances and velocities. This map spans two billion lightyears from top to bottom. The velocity field is mapped by means of tens of thousands of very thin streamlines, seeded at the positions of the catalog's galaxies. Streamlines are shown white and semi-transparent, against a black background. They exhibit a very complex pattern with multiple attractors, seen as points of convergence of the lines. A text reads Galaxies from wherever flock together.

a cosmographic map featuring the cosmological large scale structure in our local cosmic neighborhood. The density field is displayed as semi-transparent isosurfaces, colored grey for the the lower isocontour value, and colored in nuances of red for five higher levels. The resulting structure is filamentary, with high-density knots at the filaments' crossing, an architecture typical of the Cosmic Web. Three colored arrows materialize the cardinal axes of the Supergalactic Coordiante System, centered at our location. Several important actors of our local cosmography are named: Milky Way, Virgo, Arrowhead, Great Attractor, Perseus-Pisces, Coma, Arch, Hercules. The name of the astronomer leading the study is inprinted in the lower right corner of the figure, reading R. Brent Tully. All these elements are drawn against a white background.

The distribution of galaxies obtained with the Sloan Digital Sky Survey and displayed as two fan-shaped plots with Right Ascension versus redshift distances as coordinates. Galaxies' positions are shown as black points on a white background, featuring filamentary structures typical of the Cosmic Web, which describes the large-scale structure of the Universe. The two fan-shaped plots lie on top of each other, with their boundaries elegantly matching each other's. On the lower plot, running from 0 to 14000 km/s in redshift, and from 8 to 17 hours in Right Ascension, is shown the CfA2 Great Wall, with its iconic stickman-shaped distribution of galaxies. On the higher plot, running from 14000 to 28000 km/s in redshift distances, and from about 9 to 14 hours in Right Ascension, is featured the Sloan Great Wall. A caption completes this figure.
